I understand your aesthetically question who take care of the history of user interface design: many DE you’ll find on Linux are inspired by Windows and Mac OSs, and so typically Gnome is more near to mac while KDE to windows; keep in mind both are completely customizable. There are also other original Linux interfaces who brings something more exotic (old Ubuntu Unity or window managers like i3-wm) but most of these are used by few since UI’s comfort tend to unify everything.

Addednum: I really liked the old KDE4 with it’s beautiful and peculiar tablet view, now abandoned

Commercial OS tend to unify everything in a single name, Windows is the OS and - for example - the DE may be considered “metrostyle”. The distribution is Linux + selected packages (also DEs)

It’s like having a “double check” from a trusted source, they compile selected stuff from the aur so I suppose it’s a little more safe for the random user.

That’s another reason I like cachyos: they have a curated list of aur pkgs in their repo.
